Marvin find doubles facts, such as 4+4 and 1+1,on the addition table. he colors each sum. what pattern does marvin make when he colors the sums of the double facts?

Answer with explanation:

Addition table (Composition = +Addition)

+  |   1      2      3    

---|

1  |   2     3        4

2 |   3       4       5

3 |  4       5       6

The pattern that Marvin has made to find the sum of any doubles Facts is :

     ⇒  a + a = 2 × a

 For example :

→  1 + 1 = 2 × 1 =2

→  2 +2 =2 × 2=4

→  3+3= 2 × 3 =6

→  4 +4 = 2 × 4=8

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
